MECHANICAL INSTALLATION
The SulfiLogger
™
sensor can be installed in
four different ways:
a) Free hanging (liquids)
b) Fixed (liquids)
c) Inline (gases)
d) Fixed (gases)

a) Free hanging (liquids)
This mounting option is ideal for low flow
reservoirs and channels and generally suit- able for short measurement campaigns.
The SulfiLogger
™
sensor is installed at the
end of an extension pipe, attached to an an- chor point using a steel wire and suspended down into the sewage. The extension pipe ensures that the cables and connectors are protected from fouling.
To perform this installation, you must
ensure: •
That the circulation in the reservoir is suf- ficient to ensure good mixing.
•
That the sensor tip can not touch the
walls and bottom of the reservoir, espe-
cially during high flows. If there is a risk of the sensor hitting the walls, then you should perform the "fixed (liquids)" instal- lation instead.
•
That you have a suitable anchor point available to attach the steel wire to.
•
That the length of the steel wire allows the sensor to remain in the liquid at all times while the back of the extension pipe at the same time remains out of the liquid.
b) Fixed (liquids)
This mounting option is ideal for permanent
installations in low and high flow reservoirs and channels. It is similar to the "Free hang- ing (liquids)" installation in most regards but here, the extension pipe (and sensor) is fixated - not hanging in the steel wire. Unisense does not supply brackets or any other materials for this installation method. c) Inline (gases) Directly on the main pipe
The SulfiLogger
™
sensor can be installed
on a pipe stub allowing measurement in a
closed system. •
Before installing the pipe stub a
30 mm
hole must be drilled in the main pipe.
•
The pipe stub is supplied by Unisense and must be welded onto the main pipe.
•
Use a spanner (size 36) to screw the Sul- fiLogger™ sensor onto the pipe stub.
•
Beware of the pressure rating of the Sul- fiLogger
™
sensor and ensure that the
pressure pipe system does not exceed
the pressure limit.
Bypass flow using a flow cell
A portion of the flow can be di-
rected/bypassed into a flow cell on which
the SulfiLogger™ sensor is installed. •
Before the installation, please ensure that the pressure and temperature rat- ings of the bypassed flow are within the specifications of the SulfiLogger
™
sensor.
• The flow cell is supplied by Unisense. •
Use a spanner (size 36) to screw the Sul- fiLogger™ sensor onto the flow cell.
d) Fixed (gases)
The SulfiLogger
™
sensor can be mounted
in pump wells, reservoirs etc. above wa-
ter level for gas phase measurements. The outer diameter of the SulfiLogger
™
sen-
sor resembles a
1.5 "
pipe and can thus be
mounted using a standard 1.5 " pipe ring. Extension pipe installation For free hanging and fixed measurements in liquids, an extension pipe must be at- tached to the SulfiLogger
™
sensor. This fig-
ure shows the steps needed to perform this installation: •
Unscrew the three hex screws on the back of the SulfiLogger
™
sensor and re-
move the outer ring.
•
Feed the cables through the extension pipe and attach them to the connectors on the sensor.
•
Align the sensor with the screw holes of the extension pipe and screw in the three hex screws to secure the sensor to the extension pipe.
Temperature rating
The sensor is designed to withstand temper-
atures from -20
◦
C to +60
◦
C.

DANGER Exposing a SulfiLogger
™
sensor from
the X1-series for ambient tempera-
tures lower than -20
◦
C or higher than
+60
◦
C will void the ATEX certificate.
The sensor, both S1 and X1 series, performs
optimally between 0
◦
C and +40
◦
C.
Disassembly
We do not recommend you to disassemble
the SulfiLogger™sensor.

IMPORTANT NOTE Disassembly of the sensor will void the
warranty and render the sensor non-
functional.

DANGER Disassembly of a SulfiLogger
™
sensor
from the X1-series will void the ATEX certificate.
